To all whom it may concern:

Be it known that I, CLINTON E. LARRA EE, residing at Binghamton, county of Broome,

' and State of New 'York, have invented certain new and useful Improvements in Duplex Counters, of which the following is afull,

' clear, and exact description.

In extensive manufacturing enterprises, modern practice requires that records of the operatzon of each machine, and of the money value of the work performed by such m awill require two essentially distinct types of adapted for attachment to a great variet of apparatus for producing them.

0 provide for. the more economical and effective attainment of such results I have devised aform of counter, which is, in effect,

a dual instrument but of very simple construction and mode of operation, which is machines and which will not only pro uce and constantly exhibit the desired registrations, but permit cards to be printed orpunched to record their condition at anytlme. In this device resides the invention which forms the subject of'my present ap- I plication :for Letters Patent.

'To convey a clear understanding of the. nature and purposes of the invention, I will assume any type of machine the operations of which maybe registered by a simple form of counter which registers the number of cycles of such machine corresponding to the-production of articles made thereby.

Such av counter is attached to the machine.

7 and in conjunction with it a second counter "1s employed geared to the main operating shaft or element of -the} same by. means which impart to said second counter amov'ementfrelatively faster I or slower than the first in an desired ratio so as to produce a record di erent from but corres onding to thatof the first counter. As a ove stated the first counter'will r'e ister the-number, say, ofpieces made by t e machine, while the second will register themoney value of such pieces, or the amount with which the operative is to be credited for making them or other and similar data.

Such a device requires certain parts and appurtenances of peculiar construction to adapt 1t for practical use and operation,

and these will be more fully described by I reference to the drawings hereto annexed mechanism in elevation, the casing being shown in section;

' Figs. 11, 12, 13 and 14 are detailed views of devices used in the counters for transmitting movement from one registering disk .to another.

Fig. 15 is a central vertical section of a counter adapted to print on a card a record of its condition and driven electrically.

liig. 16, is a front'elevation of the same, an

Fig. 17 is a view of a printed card.

The counters are contained in' casings 1 and 2, having displayopenings to exhibit the index wheels.- The instruments are desirably mounted on a plate 8, which may be attached in any convenientway to a given machine, and for indicating the means by which the counter is o erated. I have shown an oscillating cran a rod 5 from some movable part of the machine is connected. The movements of the arm l'are transmitted to a shaft 6., (Fig. 1) which'carries a pawl 7, engaging the teeth of a ratchetwheel 8.

This wheel 8 is secured to a twenty tooth arm 1 to which gear wheel 9, that engages with a pinion 10,

on the shaft 11, that extends entirely through the first counter, and is connected by suitable gears inan intermediate gear in which event a pawl similar to the pawl 7,

cry of the or some equivalent device is used to operate it. The said shaft 13,'however, carries a gear 10 corresponding to that in the first counter and by this means imparts motion to the units Wheel 9 of the second counter corresponding to that of the first.

This. means is the same in each counter. The ratchet wheel 8 and gear 9, are secured to a units index dial 16, and for each movement of the power wheel of one tooth and of the latter of two, this dial is turned through one figure or character space. Then in order to move the dial of the next higher order of units one space for every complete revolution of the dial below it, I employ the means more particularly illustrated in Figs. 5 and 11 to 14.

On the side of each dial opposite to that to which the gear wheels 9 are attached is a disk 17, and a cam 18, both rigid with the dial. Attached to the disk 17, there is a two-toothed sector 19, the space between the teeth of which overlies a similar and somewhat deeper indentation 20 in the disk 17. Alongside the disk on a transverse shaft 21 are a series of loose sleeves 22, having two gears side by side. The left hand gear, shown in Fig. 12, is double, having three teeth on one side and six on the other, the former being shown in Fig. 13, the latter m Flg 14:, and the disk with its two toothed sector is so placed relatively to this double gear that the sector is on the plane of the six toothed iportion while the disk itself is in the plane 0 the three toothed portion.

From this it follows that the gear sleeves 22 are normally locked against rotation by the engagement of the three toothed portlons of the gears with the adjacent periphdisk, but when, by the rotation of the disk, the two 'toothed sectors are brought into engagement with the six toothed portion of gears 23, the said gears .are moved because at that time a tooth on the three toothed portion falls into the indentation in the periphery of the disk. The sleeve 22 is thereby turned and as it carries a gear 24 that engages with a gear 9 on the dial of the next higher order of. units the said dial is turned one space for every revolution of the dial next below it in order. I I c I have described a specific construction ofcount'er which in itself is not a part of my invention, but which may be very greatly varied in construction, design and operation. It should, however, have either the cams 18, or some equivalent means the position of which will vary with and correspond to the position of the index dials, in order to afford a ready means for obtaining from each counter a punched or printed record of its exact condltion at any time. In the present case I employ with each cam 18, a pivoted le ver 25, having a pin 26, projecting sidewise from its lower end and adapted to be forced toward the cams, so as to have a movement of greater or less extent according to the position of said cams. Then when a record of the counters is to be taken any proper or known form of card punching mechanism is suspended from hooks 14 and 15, or 15 and 27, (Fig. 1) and operated to force fingers 28, as indicated in dotted lines in Fig. 4: through openings 29, in the front of the counter casings where they engage with the pins 26, and force the levers 25, against the cams. The extent of the movements of the fingers 28 thus permitted determines the position or the character of the holes punched in the card, and these latter will be an exact and true representation of the condition of the counters at any time when the record was taken.

The gear box 12, between the two counters is a casing that is adapted to be secured by screws 30 to the two counter casings. It contains a two part shaft 31, 32 with ends adapted to engage with the ends of the counter shafts 11 and 13 as shown in Fig. 9, and. each part of said shaft carries a gear wheel 33, or 34. These may be of widely diflering diameters according to the relative speeds required in the two counters. In Fig. 8, for example, the gear 33 is not very much larger than gear 34, and the intermediate gears on a counter spindle 35, by which the movement of 33 is transmitted to 34, bear substantially similar relations with the result that the main shaft of the right hand counter is revolved at say at twice the speed of the shaft 11.

In Fig. 9, on the other hand the relations of the gears is adjusted so as to result in a different speed ratio, say six to one, and similarly the relations may be varied to any other desired extent. The gear box is also constructed and designed to be reversed, that is to say, it may be turned to connect the shafts 11 and 13 so that the latter will turn slower than the other and in this and other well understood ways any relative speed of connecting plates or bars 36 with the annashown Figs. 15 to 17. In this case the shaft '6 which operates the pawl 7, is oscillated by ture 37 ofan electr c-magnet 38 arranged in the counter casing. v The magnet is operated cient width to include by an electric circuit 39', controlled by a rotary switch 40 moved by any suitable source of power that may be desired, such as a.

clock. In such case the counter isoperated say ten times an hour .or any other fraction of time and the record which it displays or which may be takenfrom it will indicate a given elapsed time.

The second counter under such circumstances will be arranged to show the money value of the operators service for such time grtany other equivalent and corresponding To facilitate the taking of records from A device of thekind hereinbefore described has a wide field of usefulness in many manufacturing enterprises in which.

computations and tabulations of practical results, costs andthe like areessential in the conduct of the business. It saves both mechanism. and time in securing its intended. re-

sults, and can be made in a very small cost.

. What'I claim-iszl. A recording and computing machine comprising in combination two counting mechanisms in fixed relation and adapted for great numbers at attachment to and operation by a given machine, one adapted to be operated by or in accordance withthe operation of such machine, an independent'detachable connecting device, connectin gears of predetermined ratios therein, a apted for applications to and use with the counters and when attached thereto to connect by the said gears the driving or operating means of both counters, whereby the movement imparted by one to the other will vary according to the character of the intermediate gears.

. 2. A duplex counting or recording mech- 'anism, comprising in combination, two counters mounted on a rigid base and adapted'for attachment to and operation by a givenmachine, the one operated by or in accordance with the operations of said 'machine, the
